I am searching for Heinrich Dose born December 7, 1829 in Schlewig-Holstein Germany. He married Dorothea Johnson born March 29, 1829 also in Schlewig-Holstein. They came to the U.S. and farmed in Arcadia, Iowa. Heinrich died October 20, 1907, Dorothea died July 20, 1902. They are buried in the Arcadia Cemetery.
They had 7 children: Peter 1855-1922, Claus 1857-1940, Antje Sophie 1860-1914, Detlef 1863-1907, John 1868-1954, William 1869-1942, Fritz (no dates or information-he stayed in Germany.
Would like to share information with anyone who can help.
